BACKGROUND The Jefferson Scale of Attitudes Toward Physician-Nurse Collaboration (JSATPNC) has been used to measure attitudes regarding nurse-physician collaboration. However, psychometric evaluation is lacking for the nurse practitioner (NP) population. PURPOSE This study details a confirmatory approach in testing the factor analytic structure of the JSATPNC against previously reported struc...

A decade ago, sub-Saharan Africa accounted for 24% of the global disease burden but was served by only 4% of the global health workforce. The chronic shortage of medical doctors has led other health professionals especially nurses to perform the role of healthcare providers. These health workers have been variously named clinical officers, health officers, physician assistants, nurse practition...

This work deals with the design of the low{level stages of any diierential{ based optical ow algorithm. The problem is the accurate estimaton of the spatio{temporal derivatives of the moving image, to be used in the solution of the gradient constraint equation. We claim that the \tradi-tional" techniques for the partial derivatives estimation can be improved by i) exploiting all the information...

In this paper we show how the classical job shop scheduling problem can be modeled as a special class of acyclic timed automata Finding an optimal schedule corresponds then to nding a shortest in terms of elapsed time path in the timed automaton This representa tion provides new techniques for solving the optimization problem and more importantly it allows to model naturally more complex dynami...

Using the Johansen cointegration technique, we find empirical evidence of long run comovements between five national stock market indexes and measures of aggregate real activity including the real oil price, real consumption, real money, and real output. Real returns on these indexes are typically related to transitory deviations from the long run relationship and to changes in the macroeconomi...
